First embodiment
Fig. 1 is a schematic structural view of a pressure monitoring system according to a first embodiment. As shown in fig. 1, the pressure monitoring system of the present embodiment includes an output device 12 and a data acquisition device 11, and the output device 12 is connected to the data acquisition device 11.
The data acquisition device 11 comprises a flexible spreadable resistive sensor array 111, and further comprises an analog/digital converter 112, a power supply module 115, a micro control unit 113 and a communication module 114, wherein an input end of the analog/digital converter 112 is connected with the resistive sensor array 111, the micro control unit 113 is respectively connected with an output end of the analog/digital converter 112 and the communication module 114, the power supply module 115 is connected with the micro control unit 113, and the communication module 114 is used for establishing connection with the output device 12.
The resistive sensor array 111 can be made of flexible piezoresistive fabric materials, the flexible piezoresistive fabric materials can be metal-plated fiber fabrics, fabrics coated with conductive coatings, conductive leather and the like, the piezoresistive fabric materials can be made into resistive sensor arrays 111 in various shapes so as to meet the requirements of different use space sizes and shapes, for example, the resistive sensor arrays can be made into a sheet type structure, meanwhile, the materials are good in flexibility, and the use comfort can be improved. When a sensor made of the flexible piezoresistive fabric material is pressed, tensile deformation can be generated, the length is lengthened and the sectional area is reduced after the material is deformed, the impedance is measured from the two ends of the material, and the obtained impedance value can be increased, so that the sensor can be used for representing the pressure. Due to the fact that the resistive material is adopted, the size of the impedance generated when the resistive material is deformed under pressure corresponds to the current deformation size of the material, the impedance is kept continuously after deformation is finished, sensing data can be detected continuously, and therefore dynamic pressure monitoring and static pressure monitoring are achieved.
As shown in fig. 1, a cross point between a transverse portion 118 and a longitudinal portion 117 of the resistive sensor array 111 is a detection point 119, the detection points 119 are distributed in a matrix form, a pressure value of each detection point 119 is related to detection values of the transverse portion 118 and the longitudinal portion 117 passing through the detection point 119, and detection data of the transverse portion 118 and the longitudinal portion 117 are fused to obtain a pressure value corresponding to the detection point 119. The fusion may be performed by superimposing the pressure values corresponding to the crossing transverse portion 118 and the longitudinal portion 117, for example, by adding numerical values, weighting, adding a sum of squares, and the like, so that the numerical value at the detection point 119 can represent the pressure conditions of the transverse portion 118 and the longitudinal portion 117 at the same time. It can be understood that the manufacturing method and the detection method of the resistive sensor array 111 are not limited thereto, and each detection point 119 may also be an independent sensor, and only the pressure of different detection points 119 may be accurately represented.
The input of the analog/digital converter 112 is connected to the resistive sensor array 111. The data of the resistive sensor array 111 is acquired by multi-channel impedance, each detection point 119 is electrically connected to the input end of the analog/digital converter 112, and because the pressure variation speed is not fast, the analog/digital converter 112 can select a high-speed analog/digital converter, poll and acquire detection signals of different channels, and respectively convert the detection signals into voltage signals, so that multi-channel pressure data can be obtained.
The output of the analog/digital converter 112 is connected to the micro control unit 113, and the micro control unit 113 controls the communication module 114 to send the detection data to the output device 12. Preferably, the communication module 114 is a wireless module, and may be a bluetooth module, a WIFI module or a mobile network communication module, so as to meet the requirements of short-range communication or long-range communication. The power module 115 is used for providing a working power supply for the data acquisition device 11, and preferably, the power module 115 may be a rechargeable power supply, so as to avoid the arrangement of an external wire and improve the use safety.
Optionally, the data acquisition device 11 further comprises a sound sensor 116, and the sound sensor 116 is connected to the input terminal of the analog/digital converter 112. A sound sensor 116, such as a microphone, may capture ambient sounds to reflect the current scene, such as whether the baby cries, whether there is a distress sound, etc.
The output device 12 is configured to receive the detection data collected by the resistive sensor array 111, and output an image representing a pressure distribution on the resistive sensor array 111 according to the detection data. Since the detection data of the resistive sensor array 111 is continuously output, static monitoring and dynamic monitoring can be simultaneously realized, and the detection data is converted into an image which can represent the pressure distribution on the resistive sensor array 111, such as a thermodynamic diagram, so that the monitoring result can be more visually seen in real time through the display of colors and the change of the colors in the thermodynamic diagram. In practical implementation, the output device 12 may be a handheld terminal such as a mobile phone, or an output device such as a computer and a console that is configured with the data acquisition device 11.
Optionally, the output device 12 is further configured to extract a physiological index according to the detection data, wherein the physiological index includes at least one of respiration, heart rate, body movement, and sleep state. Because the detection data can be used for reflecting the pressure, the resistive sensor array 111 is made into a bed sheet form or a spreadable state, when a person lies on the bed, the pressure of the human body to the resistive sensor array 111 changes correspondingly along with heartbeat, respiration and body movement, and various physiological indexes can be extracted by monitoring the pressure change.
The specific workflow regarding the pressure monitoring system is described in detail in the second embodiment.
Meanwhile, the multichannel sensors are arranged in an array form, multichannel data are fused to generate a thermodynamic diagram, the monitoring accuracy of physiological indexes can be improved, the in-bed state of infants or target personnel can be visually displayed, and a fine pressure image can be displayed by combining an interpolation algorithm. In addition, this embodiment can whether automated inspection human body carries out automatic switch on and off in the bed, can low-power consumption wireless transmission data, carries out incident monitoring and propelling movement in real time, convenient to use, noninductive.
The pressure monitoring system of the embodiment comprises an output device and a data acquisition device, wherein the output device is connected with the data acquisition device, and the data acquisition device comprises a flexible spreadable resistive sensor array; the data acquisition device sends detection data acquired by the resistive sensor array to the output device, and the output device receives the detection data and outputs an image for representing pressure distribution on the resistive sensor array according to the detection data. The flexible spreadable resistive sensor array is adopted to collect detection data, the use comfort can be improved, the collection of multi-channel pressure data can be achieved, the material of the sensor is simple to realize, the cost is low, meanwhile, the resistive sensor array can comprehensively collect the pressure of different positions and can achieve pressure static collection, the monitoring result is used for representing the image of pressure distribution on the resistive sensor array in a matched mode, and the monitoring result is real-time and more visual.
Second embodiment
Fig. 2 is a schematic flow chart of a pressure monitoring method according to a second embodiment. As shown in fig. 2, the pressure monitoring method of the present embodiment is applied to the pressure monitoring system of the first embodiment, and the method includes:
The structure of the resistive sensor array is as described in the first embodiment, each detection point is electrically connected to an analog/digital converter, and the analog/digital converter polls and collects detection signals of different channels and converts the detection signals into voltage signals respectively, so that multi-channel pressure data can be obtained. The detection data sent to the output device by the data acquisition device may be processed pressure data of each detection point, or may be only raw data of each detection point.
In order to realize automatic monitoring, the data acquisition device judges whether the detection data meet the preset activation condition at intervals of a first preset time length; if yes, entering an activation state, and sending detection data acquired by the resistive sensor array to an output device; if not, entering a dormant state. Optionally, the preset activation condition is that the duration of the detection data is greater than a preset threshold value for a second preset duration. The micro control unit in the data acquisition device monitors the detection data at regular time (for example, every minute), and when the detection data lasts for a second preset time length longer than a preset threshold value, for example, the detection data lasts for 30 seconds longer than the preset threshold value, it can be judged that a person lies on the resistive sensor array, so that the monitoring is automatically activated, and the acquired detection data is sent to the output device. Otherwise, if no detection data exists or the detection data does not last for the second preset time length to be longer than the preset threshold value, it can be judged that no one lies on the resistive sensor array, the device is not started at the moment, and enters a dormant state or keeps the dormant state, so that the power consumption of the device can be reduced, manual control is not needed, and better experience is achieved.
In step 220, the output device receives the sensed data and outputs an image representing the pressure distribution across the resistive sensor array based on the sensed data.
Optionally, the output device outputs an image representing a pressure distribution on the resistive sensor array according to the detection data, and includes:
determining the pressure value of each detection point on the resistive sensor array according to the detection data;
and displaying a thermodynamic diagram for representing the pressure distribution on the resistive sensor array according to the preset relation between the pressure value and the display color and the arrangement mode of the detection points.
Wherein, the corresponding relationship between the preset pressure value and the display color may be: the lower the pressure value, the colder the color, and the higher the pressure value, the warmer the color. After the pressure value of each detection point is obtained, according to the preset relation between the pressure value and the display color and the drawing principle of the thermodynamic diagram, the pressure value is converted into the color, the lower the numerical value is, the colder the color is, the higher the numerical value is, the warmer the color is, and at the moment, the visual thermodynamic diagram can be drawn according to the arrangement mode and the color of the detection points. Generally, in a static state or a moving state, different parts of a human body have different degrees of squeezing on different positions of the resistive sensor array, and the generated pressure is different, so that the thermodynamic diagram can reflect the outline of the human body and the positions of the different parts in the human body to a certain extent, and further the lying state of the human body is very intuitively reflected.
Since the number of detection points is affected by the volume of the apparatus and the cost, there may be a problem that the number is insufficient to affect the image rate, and therefore, in order to improve the resolution of the image, interpolation processing may be performed. Optionally, displaying a thermodynamic diagram for representing pressure distribution on the resistive sensor array according to a preset relationship between the pressure values and the display colors and an arrangement manner of the detection points, includes:
performing pressure value interpolation according to the arrangement mode of the detection points and the corresponding pressure values;
determining display colors corresponding to all the pressure values after interpolation according to the preset relation between the pressure values and the display colors;
and displaying a thermodynamic diagram for representing the pressure distribution on the resistive sensor array according to the arrangement mode of the detection points and the display colors corresponding to all the pressure values after interpolation.
Common image interpolation algorithms include Nearest neighbor interpolation (Nearest-neighbor), Bilinear interpolation (Bilinear), bicubic, lanczos, directional interpolation (Edge-directed interpolation), example-based interpolation, and deep learning. After the interpolation algorithm is used, the resolution of the thermodynamic diagram can be greatly improved, and the display is finer.
Optionally, after the output device receives the detection data collected by the resistive sensor array, the output device further includes:
and extracting and outputting physiological indexes according to the detection data, wherein the physiological indexes comprise at least one of respiration, heart rate, body movement and sleep state.
The pressure of the human body to the resistive sensor array changes periodically along with the breathing of the human body, pressure signals detected by the detection points form a breathing curve, a breathing rate value can be extracted through algorithm processing, and meanwhile, the thermodynamic diagram also changes correspondingly, so that a regular breathing dynamic image is generated.
Ballistocardiography (BCG) is a noninvasive, contactless, convenient means of monitoring cardiovascular function. When the heart beats, the acceleration of blood can generate mechanical shock waves, and the gravity of the human body can change when the heart shoots blood. Therefore, signals output by the detection points on the resistive sensor array can change along with the mechanical impact rule, the heart rate value can be extracted by processing through an algorithm, and meanwhile, the thermodynamic diagram can also show corresponding change, so that a regular heartbeat dynamic image is generated.
The human body sends body movement, such as turning, rising and other actions, pressure change can also be generated at corresponding detection points on the resistive sensor array, a body movement curve can be extracted through algorithm processing, and meanwhile, the thermodynamic diagram can also show corresponding change.
Whether the human body gets up and leaves can also be judged through the monitoring of the heart rate and the respiration. Wherein, after the human body rises and leaves, the pressure disappears; when the human body does not stand up and leaves, pressure exists, and corresponding pressure changes of respiration and heartbeat occur, so that whether the human body stands up and leaves can be judged.
In addition, after indexes such as heart rate, respiration rate, body movement and the like are obtained, the sleep state can be analyzed by combining the indexes, the sleep stage is established, and the sleep state and the quality can be known conveniently.
In actual implementation, the early warning of waking up can be realized by combining the indexes, and the infant nursing device is particularly suitable for nursing infants. For example, when the body movement gradually increases to a certain degree, the infant can be judged to be about to wake up, and for the infants with low ages, struggle and cry are often accompanied, so that the waking of the infant can be accurately predicted through the indexes, and parents can be timely reminded to pay attention to the sleep state of the infant in advance.
Optionally, when the data acquisition device further includes a sound sensor, the output device receives sound data acquired by the sound sensor, judges whether the current scene is a preset scene according to the sound data, and outputs prompt information if the current scene is the preset scene. The preset scenes are, for example, the infants cry and call for help, whether the infants cry and call for help exist can be judged through sound identification, and the abnormality can be found in time.
The flexible piezoresistive sensor array adopted by the embodiment can not only realize the acquisition of multi-channel pressure data, but also detect static pressure data, and the material of the sensor is simple to realize and low in cost. Meanwhile, the multichannel sensors are arranged in an array form, multichannel data are fused to generate a thermodynamic diagram, the monitoring accuracy of physiological indexes can be improved, the in-bed state of infants or target personnel can be visually displayed, and a fine pressure image can be displayed by combining an interpolation algorithm. In addition, this embodiment can whether automated inspection human body carries out automatic switch on and off in the bed, can low-power consumption wireless transmission data, carries out incident monitoring and propelling movement in real time, convenient to use, noninductive.
